Parental styles,gender and the development of hope and self‐esteem

We examined the developmental trajectory of trait hope and self‐esteem over 4 years and the impact of gender and perceived parental styles on these trajectories. Participants were 884 high school students. There was a general decline in hope and self‐esteem over time, with females declining more rapidly than males. Girls had higher hope than boys in Grade 7, but lower hope by Grade 10. Perceived parental authoritativeness at Time 1 was related to high hope across the 4 years, whilst perceived parental authoritarianism was related to low self‐esteem. We discuss the importance of perceived parental styles for adolescent well being, as well as possible explanations for changes in hope and self‐esteem. Copyright © 2008 John Wiley & Sons, Ltd.     

腰椎间盘突出症患者MED术前心理状态调查与分析

为了研究腰椎间盘突出症患者行MED微创治疗前的心理状况,对442例行MED手术治疗的患者应用焦虑自评量表（SAS）、抑郁自评量表（SDS）进行术前心理评估。结果显示MED微创治疗前患者SAS、SDS测量分明显高于常模组。患者性别、年龄、婚姻状况、文化程度、病程长短等都与心理状况的改变相关。有34.9%的患者SAS得分和36.7%的患者SDS得分显示阳性。因此,临床骨科医师应重视心理因素的作用,在MED术前应对患者进行心理状况评估,并对心理状况较差的患者进行术前干预,才能取得更好的临床疗效。     

How to learn the natural numbers: inductive inference and the acquisition of number concepts

Theories of number concepts often suppose that the natural numbers are acquired as children learn to count and as they draw an induction based on their interpretation of the first few count words. In a bold critique of this general approach, Rips, Asmuth, Bloomfield [Rips, L., Asmuth, J. & Bloomfield, A. (2006). Giving the boot to the bootstrap: How not to learn the natural numbers. Cognition, 101, B51-B60.] argue that such an inductive inference is consistent with a representational system that clearly does not express the natural numbers and that possession of the natural numbers requires further principles that make the inductive inference superfluous. We argue that their critique is unsuccessful. Provided that children have access to a suitable initial system of representation, the sort of inductive inference that Rips et al. call into question can in fact facilitate the acquisition of larger integer concepts without the addition of any further principles.     

涵义语义与关于概称句推理的词项逻辑

概称句推理具有以词项为单位的特征并且词项的涵义在其中起到了重要的作用。已有的处理用A一表达式表达涵义,不够简洁和自然。亚里斯多德三段论是一种词项逻辑,但它是外延的和单调的。这两方面的情况使得有必要考虑新的词项逻辑。涵义语义的基本观点是：语词首先表达的是涵义,通过涵义的作用,语词有了指称,表达概念。概称句三段论是更为常用的推理,有两个基本形式GAG和Gaa。在涵义语义的基础上建立的系统GAG和Gaa是关于这两种推理的公理系统。     

Facet-like Structures in Computer Science

This paper discusses how facet-like structures occur as a commonplace feature in a variety of computer science disciplines as a means for structuring class hierarchies. The paper then focuses on a mathematical model for facets (and class hierarchies in general), called formal concept analysis, and discusses graphical representations of faceted systems based on this model.

Effects of Computer-Based Fluency Training on Concept Formation

This study provides a preliminary analysis of how the techniques of fluency training can be combined with systematic concept instruction to improve the learning of complex verbal concepts. Fluency techniques, which require the learner to respond accurately at high rates, have typically focused on definition learning when teaching concepts. Instructional psychologists, however, recommend multiple exemplar training for conceptual instruction. To examine this issue, 41 undergraduate students completed a computer-based instructional module on logical fallacies. Participants were assigned to one of four groups, with the modules for each group differing only in the type of practice provided—either fluency or practice with either examples or definitions. Examination of posttest scores revealed significantly higher scores for participants in the examples groups than those in the definitions groups, but low experimental power prevented a clear conclusion to be drawn about differences between the fluency and practice groups. Implications of results and several methodological issues relevant to this area of research are discussed.     

论自我同一性概念的整合

自我同一性是西方心理学一个重要的概念,但至今没有一个普遍接受的定义。通过对自我同一性概念内涵不一得归因分析,指出了整合自我同一性概念应关注的几个范畴,进而提出自我同一性是一个与自我、人格的发展有密切关系的多层次、多维度的心理学概念。本质上,它是指人格发展的连续性、成熟性和统合感,它包含三个层面的内涵：(1)最基本的层面,即ego-idernity;(2)个人同一性;(3)社会同一性。     

中文新异组合概念的解释及影响因素

通过分析600名中国大学生对32个概念组成的160个新异组合概念的解释,考察了中文名词-名词组合概念的解释策略及影响因素。结果表明：⑴关系解释和属性解释是两种主要的解释策略;⑵第一个子概念具有显著属性的组合概念得到更多的属性解释;⑶子概念之间相似性的高低不影响属性解释出现的比率,但影响关系解释出现的比率;⑷生物组合概念比人造物组合概念得到更多的属性解释。其中的新发现既不支持关系竞争理论,也不支持双重加工理论,引出了有待研究的新问题。     

团体认知影响数学概念结构表征的实验研究

概念结构表征一直是认知心理学研究的重要内容。本研究以团体及表征理论为基础,通过设计不同的团体认知条什来研究认知交互作用对概念结构表征的影响。实验结果表明不同的团体认知表现出了不同的认知交互,对概念结构表征也产生了不同的影响。     

4～5岁儿童对书面数符号的表征和理解能力的发展

本研究对61名中班儿童的书面数符号表征和理解能力进行了跟踪调查。一年中三次个别面试的结果表明,约40％的4岁儿童已能运用1—10的书面数符号表征数量。至中班末期,大多数5岁儿童能够较熟练地运用至少1一17的书面数符号来表征数量,尽管其中有人在两位数的表征和数字的正确写法上有困难。儿童的书面数符号表征与他们的基数概念发展水平密切相关。大学附属幼儿园4—5岁儿童的书面数符号表征能力好于为工人家庭服务的幼儿园儿童的能力。
